SPECIFICATION forming part of Letters Patent No. '736,37 5, dated August 18, 1903.

" A j Application ala August 8,1902. VStriano."113,872. (No man Beit known that LWILLIs I-I. FIsHnR, a citizen of the United States, residing at Kansas City, in the county of Jackson and'State of Missouri, have inventednewand useful Im-A provements` in W'all Construction, of which the following` is a specication'.

My invention relates to that y'class of wall and other constructions in which blocks, slabs,

or tiles are made of concrete or cement for the 'construction of buildings or walls.

My invention consists in the` novel forms and constructions of these blocks, slabs, or tiles, novel and practical devices for attaching veneering blocks, slabs, or tiles to the building blocks, slabs, or tiles, novel and practical devices for attaching veneering blocks, slabs, or tiles to steel, brick, or wooden framework, devices forholding embedded fastening devices in position in the blocks while the blocks are under construction, also for forming recesses adjacent to said devices for the purpose hereinafter described, devices for joining these blocks, slabs, or tiles together and at the same time attaching them toa framework.

AReferring now to the drawings, Figure 1 is a perspective view of a preferred form of construction block provided with embedded Wires. Fig. 2 is a longitudinal section of such a block, exposing the wires. spective view of a preferred form of corner construction-block having embedded wires.

. Fig. i is a section of such a corner-block;

exposing the wires. Fig. 5 is a plan view of a portion of a wall constructed of the blocks shown in Figs. l and 3, showing also several veneering-blocks in position. Fig. Gis an enlarged plan view of a construction block having a modified fastening device with two veneering-blocks attached thereto. Fig. 7is an enlarged perspective view of a portion of said fastening device. FigfS is an enlarged perspective view of amodiiication of the piece shown in Fig. 7. Fig. 9 is atop or bottom edge view, partly in` section, of a veneeringblock beforeassembling `ina wall.- Fig. 1Q

'is an end elevationof the block lying .horizontally. Fig. 11 is an elevatiouof theinner side of one of the jointfmakers. `Fig-12 `is a Fig. 3 is a perplan view of a veneering-block and part of an adjacent block, said blocks being connectedby a dowel-pin. Fig. 13 represents a veneeringblock lying horizontally in its mold, the mold being in section.

Figs., 1 and 2, represent a preferred formi of my angular construction-block. The body 1 of the block is provided with ribs 2, which are adapted tto form, in connection with veneering-blocks 3, airchambers in the wall, as shown in Fig. `5. The ribs 2 may be of any sired. 4 is the top or bottom of the block. The middle rib 2 is made thicker than the ri bs at the ends of the block, and formed inthe oluterface of the middle rib is a groove G, which will bevertical when thel block is in position in the wall. The outer edges of the end ribs 2 may be chamfered, as at 7.

Fig-3 represents a corner-block 8, adapted to be employed in connection with the form of block shown in Fig. 1. This corner-block When in position forming aportion of a corner of a wall appears in plan, as shown in Fig. 5.

9 is a recess to provide an air-chamber, as shown in Fig. 5.

It will be observed that the corner-block forms one of the air-chambers of the wall and a solid corner-column which will bear greater weight without crushing than if it were constructed hollow. The external faces of these corner-blocks may be molded with designs .as a trimming to brick veneerings, if desired. h Upon the wall proper, formed by the construction-blocks 1, are attached. the outer or veneering blocks 3, a preferred form of which is shown in Figs. 5 and 6. Each end of each veneering-block is beveled or recessed, as shown at 10.

ends of thewire or wires mightproject from one of the outeredges 13 and from the inner angles of "recesses 14, in which the ends of two ofthe veneering-blocks would be seated.

A variety of devices for securing thevef length, according to the thickness of wall de- Ico Each veneering-block will be provided with devices of some kind, so located that when the veneering-block is placed in its permanent position against the ribs of the construction-blocks the wires projecting from the latter will be adjacent to the said devices and may be attached thereto, which will secure the veneering-block in position. One of the preferred forms of such devices for the veneering-blocks is shown in Figs. 9 and 12. Embedded in each end of the veneering-block 3 are two non-metallic tubes 15. Each end of the block is recessed substantially as shown at 10, and the ends of said tubes 15 project from said recesses, as shown, but do not extend as far longitudinally as the ends of the block. Pins or dowels 16 *are inserted into the tubes 15 when the blocks 3 are being built upon the wall, and the projecting wires from the construction-blocks 1 are curled around said pins 16. This is done before the ends of the two adjacent veneering-blocks are set together. Then the wires are thus fastened, the next veneering-block is placed so that its tubes 15 will receive the pins or dowels 16, projecting from the adjacent block, and is pushed toward said adjacent block un til their ends are in abutment, or a narrow space may be left between their ends, if preferred.

Another style of fastening device for attaching the veneering-blocks to the construction-blocks is illustrated in Figs. 6 and 8. 17 designates construction-blocks, and 3 designates veneering-blocks. The veneering-blocks are provided with the embedded tubes 15 described above. Embedded in the middle rib 17 of the construction-block 17 is a bolt 19, which projects from the outer face thereof. One of the veneering-blocks' 3 is placed in position with its end about even with the bolt 19. A strip of metal 20, provided with a hole 21, which is slipped over the bolt .19, is placed with its edge against the recessed end of the block 3, outside of the tubes 15. Thena nut 2 2 is screwed on the end of the bolt to contact with the strip 20, but not far enough to bind upon the strip. Then the adjacent block 3 is pushed longitudinally toward the aforesaid block 3, which causes its tubes 15 to insert themselves behind the strip 20, as shown in Fig. 6. Of course two or more bolts 19 may be embedded in each rib 17', and the strips 2O may be shaped as shown in Fig. 8 instead of iiat.

A feature of my invention to which I attach great importance'is illustrated in Figs. 9, 10, 11, 12, and 13. The feature referred to is a wooden or metallic bar 23, two of whichy are used in the manufacture of each veneeringblock 3. In order to explain the action of these bars 23, it is expedient to represent a small portion of a mold in which these blocks are formed and pressed.

In Fig. 13, 24 designates the bottom plate of the mold, and 25 the ends thereof. 3 is one of the fully-formed veneering-blocks in the position in which it was molded. Before the material for the block is placed into the mold two of the aforesaid bars 23 are placed in the respective ends of the mold, in the corners thereof, as shown. In each of said bars are two (or more) recesses 26, which are adapted to receive and hold firmly the ends of the short pieces of tubing 15 mentioned heretofore. In each recess 26 of each bar 23 a tube 15 is inserted in the position shown by Fig. 9. Then the soft material is placed into the mold, filling the space around said tubes and bars, and is highly compressed, (by means not shown,) forming the iiat block `The ends of the mold are removed, and the bars 23 will of course adhere to the block by meansof engaging the ends of the tubes 15. The bars 23 serve to hold the embedded tubes 15 in position in the green block until the block hardens. W'hen the block has hardened suiciently, but not until the block is in position upon a wall ready for attachment thereto, one

of the bars 23 is removed from one end of the block by drawing it in the direction of the arrow in Fig. 12. The inner edge of the bar is beveled, so that it will draw from and will not chip the block. Thus one-half (more or less) of the end of the block is left recessed, for the purpose already described. When the other bar 23 is detached from the opposite end of the block a similar recess is left in that end of the block. The bars 23 are indispensable as means for holding the embedded tubes 15 in position after the blocks have been removed from their mold.V

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A construction block or tile provided with angular ribs, a groove in one of said ribs, and a fastening device embedded in the block or tile and projecting from said groove; substantially as described.

2. A construction block or tile provided with angular ribs, said ribs having beveled edges, and fastening devices embedded in the block or tile and projecting from said beveled edges; substantially as described.
